Here is the DOPPLER ER2 variator with clutch, it is the cheapest complete variator on the market. It uses a roller system unlike most of the other variators which on 103 SP / MV / MVL / VOGUE… Uses a weight lifters system. This model has rear columns and a special cheek, this allows it to preserve part of your original clutch and therefore not to be in direct gear.
This variator was tested by our team and it turned out to be really high performance !!! The cut of the cheeks is well seen, the supplied rollers are well studied (a heavy set for the torquey engines, a light play for the powerful engines at high speed). We will however recommend an adjustable mainspring like the Doppler, and a DOPPLER or MALOSSI belt in perfect condition! This variator is still fragile, the wear of the cheeks with a belt in bad condition or a badly stuck motor will be fast! We also had a small problem with a very powerful motor on the column supports which can be removed on certain series, problem solved thanks to a drilling / threading with groin / 3mm grub screw on each side.
As on all the variators, there is a small defect which with some tinkering is solved very quickly. We will say that on an original motor or well equipped, this variator if it is well accompanied and mounted will not have any problems. This vario will not, however, accompany an overpowered engine very well. It offers really enormous acceleration, the rise and decent is good longitudinal, the settings are not very complicated, it is a good variator. We could still have gained in acceleration with a smaller diameter barrel (25mm like the VARIOTOP MALOSSI) but this variator preserves a big advantage, it is very light !!! We recommend it with a well-prepared clutch (star, disc, etc.).
